Disagree.
I, for one, will never forget that pic of Rubio at the mic and Schumer at his side.
Schumer’s look of self-satisfied smugness was unmistakable.
As far as I can tell, that's Schumer's standard look - when he smiles, he always looks like the villain in a B-movie who's rubbing his hands in glee that he's just committed some particularly vile atrocity. He can't help looking the way he does, the way Rubio can't help looking so boyishly handsome that fans fall all over themselves making excuses for him. Schumer did not con Rubio into doing something Rubio did not believe in - Rubio merely did what he had always wanted to do after he convinced himself (presumably after some agonizing about the impact on his political future) that his aura of boyish innocence would keep his fans on board no matter what he did. I think he will turn out to have been right - his poll ratings are above 50% and the odds are good that he will be re-elected. Even a presidential nomination might not be out of reach - his Floridian fans seem rabidly supportive, and if Chris Christie, an amnesty proponent, is a viable candidate, Rubio, who's way more conservative (aside from amnesty), is certainly the lesser of two evils.
